FIG. 2 is an exploded perspective view of the earset in some embodiments. - As shown in
FIG. 2 , anearset 10 is a wired earset that comprises arear surface case 100, afront surface case 200, asoundproof housing 300, and anear pad 400. - A
rear case 100 forms an exterior of anearset 10 and is connected to acable 60 inFIG. 7 , and thecable 60 is combined with a connector (not presented) connectible with external device. Also, a wireless earset is directly connectible to a Bluetooth body in an electrical manner or a mechanical manner. - A
front surface case 200 is a part inserted into the inside of an ear, which is coupled with arear surface case 100 to form a case. Afront surface case 200 contains acase body 210 removably combined with arear surface case 100 and aprotrusion portion 220 that protrudes toward the outside of a protrusion portion. The inside of thecase body 210 and the inside of theprotrusion portion 220 communicate with each other. In other words, thefront surface case 210 and theprotrusion portion 220 are integrated having a penetrating large hole. - A
rear surface case 100 and afront surface case 200 are, in order to prevent external noise from flowing into the inside of a case, obturated by at least one of the following: a rubber ring, an adhesive, or an interference fit. For an example, as shown inFIG. 2 , aring installation groove 120 is formed on the border of therear surface case 100 where the inner side of a rubber ring is inserted and installed, and a ring sticking groove (not presented) is formed on the inner border of the engaging surface of thefront surface case 200. - A
soundproof housing 300 is a form of combination of a firstsoundproof housing 301 and a secondsoundproof housing 302 and is coupled within a space of arear surface case 100 and afront surface case 200, while in its inside components such as amicrophone 40 and aspeaker 30 that transceive sound. - A soundproof housing blocks an echoing and a howling that occur by an inflow of external noise through a
front surface case 200 and arear surface case 100 and reduces oscillation noise by aspeaker 30 and amicrophone 40, thus improving a quality of sound. Detailed description of it will follow. - An
ear pad 400 is installed at afront surface case 200, that is, aprotrusion portion 220 so as to thefront surface case 200 is easily inserted into an ear. Theear pad 400 is made of elastic materials such as silicon or rubber. - An
ear pad 400 contains apad body 410 installed at afront surface case 200 and a plurality ofsound insulation projections 411 that prevent noise from flowing into an ear from an externality and also prevent sound delivered into the inside of the ear from escaping to an externality. - Also,
sound insulation projections 411 increase friction within an ear so as to let anearset 10 adhered to an external auditory canal and make theearset 10 not easily removed from the ear, thus enabling its user to make a call or listen to a song even during an exercise. -
FIG. 3 is an exploded perspective view that magnifies a soundproof housing inFIG. 2 ,FIG. 4 is a perspective view for a bottom of a soundproof housing inFIG. 3 , andFIG. 5 is a perspective view of a soundproof housing inFIG. 3 seen in another direction. - As shown in
FIG. 3 , asoundproof housing 300 comprises a first soundproof housing and a second soundproof housing removably combined with the first soundproof housing and coupled with the inside of the front surface case. - For an availability of assembly and a blocking of external noise and an effectual delivering of sound signals received from the inside into a user's external auditory canal, a
soundproof housing 300 is made of sound absorbing materials, plastics, rubber or silicon. - Also, a first
soundproof housing 301 and a secondsoundproof housing 302, in order to block an inflow of noise, are obturated by at least one of the following: a rubber ring, an adhesive, or an interference fit. For an example, as shown inFIG. 3 , a rubberring installation groove 311 on which a rubber ring (not presented, see 500 inFIG. 2 ) is installed is formed on the inner border of the engaging surface of a firstsoundproof housing 301 and a secondsoundproof housing 302. - A speaker 30 (see
FIG. 8 ) and a microphone 40 (seeFIG. 8 ) are accommodated and installed in an inner space between a firstsoundproof housing 301 and a secondsoundproof housing 302, and for accommodating and installing them, a housingmain body 310, aspeaker accommodation groove 330 for accommodating aspeaker 30 and amicrophone accommodation groove 340 for accommodating amicrophone 40 are formed at the secondsoundproof housing 302. - The
speaker 30 has various types, for example, a closed and balancedarmature type speaker 30 that has ampler sound support than adynamic speaker 30, or apiezoelectric type speaker 30. Themicrophone 40 has also various types, for example, adirectional microphone 40 that has a hall on the rear surface of an input end of the microphone. - As shown in
FIG. 4 , aspeaker accommodation groove 330 has a form dented with a constant depth on the center of a housingmain body 310. Anoutput end 31 of aspeaker 30 is adjacent to thespeaker accommodation groove 330, and thespeaker accommodation groove 330 has aspeaker output hole 331 communicating with afront surface case 200. - A
microphone accommodation groove 340 has a form dented with a constant depth at a distance from thespeaker accommodation groove 330 so as to accommodate amicrophone 40. An input end 41 of amicrophone 40 is adjacent to themicrophone accommodation groove 340, and themicrophone accommodation groove 340 has a microphone input hole communicating with afront surface case 200. - It is noted that the
speaker accommodation groove 330, thespeaker output hole 331, themicrophone accommodation groove 340 and themicrophone input hole 341 presented in the drawings are just exemplary to the present disclosure, and that their form, direction, location, number and size are modifiable in some embodiments. For an instance, a blockade (not presented) is located between ac. - A
soundproof housing 300 with the composition aforementioned is installed within afront surface case 200 so that sound is clearly transceived through aspeaker output hole 331 and amicrophone input hole 341. - For an example, the
outer edge 221 of aprotrusion portion 220 of afront surface case 200 has penetration holes (not presented) corresponding to aspeaker output hole 331 and amicrophone input hole 341, and the rest is obturated so that external noise is blocked. In this case, aspeaker output hole 331 and amicrophone input hole 341 of asoundproof housing 300 are hard to correspond to the penetration holes (not presented) formed on theprotrusion portion 220 of thefront surface case 200 and the matching could be not correctly done. - Thus, in order that the
soundproof housing 300 is tightly combined within theprotrusion portion 220 of thefront surface case 200, a housingmain body 310 protrudes long toward the inside of theprotrusion portion 220 of thefront surface case 200. For an instance, as shown inFIG. 5 , a protrusion portion forinsertion 320 corresponding to the inner form of theprotrusion portion 220 of afront surface case 200 is formed on the secondsoundproof housing 302. - Ends of the
speaker output hole 331 and themicrophone input hole 341 are extended at the end of the protrusion portion forinsertion 320. Therefore, if a secondsoundproof housing 302 is installed at afront surface case 200, the protrusion portion forinsertion 320 of the secondsoundproof housing 302 approaches within the neighborhood to the penetration holes (not presented) formed on theouter edge 221 of aprotrusion portion 220 of afront surface case 200 and corresponds thespeaker output hole 331 and amicrophone input hole 341 within a short period. - Meanwhile, the input guiding portion abovementioned, not presented in detail, are arranged on a
front surface case 200 as well as asoundproof housing 300. - For an example, an input guiding portion is formed to be indented and stepped on the
protrusion portion 220 of thefront surface case 200 and guides input signals from the ear so as to be adjacent to the penetration holes (not presented) corresponding to themicrophone input hole 341. Herein, since the penetration holes (not presented) formed on theprotrusion portion 220 contain a rear microphone hole (not presented) corresponding to back holes 322 and 323 described later, the input guiding portion can be formed on a protrusion portion adjacent to the rear microphone hole. - Furthermore, when a
soundproof housing 300 is composed with the protrusion portion forinsertion 320 abovementioned, since the one-to-one correspondence between each hole of thefront surface case 200 and the secondsoundproof housing 302, it is possible to make theouter edge 221 of aprotrusion portion 220 of afront surface case 200 in an open form with no penetration hole. - In other words, a
speaker output hole 331 and amicrophone input hole 341 located in the end of the protrusion portion forinsertion 320 of thesoundproof housing 300 inserted intoprotrusion portion 220 of thefront surface case 200 is directly exposed to theouter edge 221 of aprotrusion portion 220 of afront surface case 200, thus playing a role in an outer surface of theprotrusion portion 220 of thefront surface case 200 aforementioned. Therefore, a user more easily assemble thefront surface case 200 and the secondsoundproof housing 302. - Meanwhile, a
display 350 is formed that informs a direction for combination with the front surface case in addition to the abovementioned form. For an instance, thedisplay 350, as shown inFIG. 5 , has an indented form on the side of asoundproof housing 300, or it uses indications such as a protruded projection or signs, letters, etc. Also, a display is formed on thesoundproof housing 300 of thefront surface case 200. - Thus, checking a combination of a
soundproof housing 300 and afront surface case 200 visually, a user more easily combine the two. -
FIG. 6 is a perspective view for a bottom of a soundproof housing inFIG. 3 in another embodiment,FIG. 7 is a perspective view of a second soundproof housing in another embodiment,FIG. 8 is a cross section where the earset inFIG. 2 is combined, andFIG. 9 is a magnified drawing for the principal part ofFIG. 8 . - Meanwhile, if a
speaker 30 is installed in aspeaker accommodation groove 330 formed within the inside of asoundproof housing 300 and amicrophone 40 is installed in amicrophone accommodation groove 340, each of aspeaker output hole 331 and amicrophone input hole 341 should have anoutput end 31 of aspeaker 30 and aninput end 41 of amicrophone 40, respectively, in a right position. - For the purpose above, in another embodiment, an
output guiding portion 330 a formed to be indented and stepped on aspeaker accommodation groove 330 compared to thespeaker output hole 331 so as to guide output signals from the output end of thespeaker 31 into thespeaker output hole 331 is formed in a secondsoundproof housing 302 a. - For an example, an
output guiding portion 330 a is located in the inside 331 a of thespeaker output hole 331 and is formed as a groove in a border form indented with a constant depth so as to embrace of the outside of thespeaker output hole 331. - And, as shown in
FIG. 7 , anoutput guiding portion 330 b embraces thespeaker output hole 331 of theoutput guiding portion 330 b, and is formed protuberantly to its outside. - Therefore, an
output guiding portion 330 b prevent noise caused by speaker output since it is tightly adjacent to the inside (not presented) of afront surface case 200 and makes easy speaker output. - Furthermore, the
output guiding portion 330 b tightly adheres to the inside of thefront surface case 200, thus waterproofing is easily performed. - Moreover, an
input guiding portion 340 a is formed to be indented and stepped compared to amicrophone input hole 341 at amicrophone accommodation groove 341 so as to guide input signals from an input end of amicrophone 41. Likewise, aninput guiding portion 340 a is located in the inside 341 a or outside 341 b of themicrophone input hole 341 as the same form of anoutput guiding portion 330 a, and it is formed as a border groove dented with a constant depth so as to embrace the outside of themicrophone input hole 341. - Of course, it is also noted that a form, size, depth, etc. of the
output guiding portion 330 a and theinput guiding portion 340 a aforementioned is embodied in a various way. - Meanwhile, second
soundproof housings back hole microphone 41 and back hole guiding portions (not presented) formed to be indented and stepped on the inside 332 a and 333 a or the outside 332 b and 333 b. - It is also noted that back hole guiding portions is embodied like the
output guiding portion 330 a and theinput guiding portion 340 a, and its form, size or depth is embodied in a various way. - Likewise, since a
soundproof housing 300 contains anoutput guiding portion 330 a, aninput guiding portion 340 a and back hole guiding portions thus forming a guiding portion, if aspeaker 30 and amicrophone 40 is equipped within thesoundproof housing 300, sound is clearly transceived by the guiding portion, even the holes does not fit to each other. -
FIG. 10 is an exploded perspective view of the earset in another embodiment. - As shown in
FIG. 10 , anearset 10 a, unlike thewired earset 10 abovementioned, is a wireless earset in a formed of Bluetooth, etc. Theearset 10 a also comprises arear surface case 100 a, afront surface case 200 a, asoundproof housing 300 and anear pad 400 a, The detailed description for the earset is the same as the description above. - Meanwhile, the earset aforementioned in some embodiments includes a
soundproof housing 300, aspeaker accommodation groove 330, amicrophone accommodation groove 340, amicrophone input hole 341, aspeaker output hole 331 and aback hole soundproof housing 300 comprises a firstsoundproof housing 301 and a secondsoundproof housing 302, and the secondsoundproof housing 302 comprises thespeaker accommodation groove 330, themicrophone accommodation groove 340, themicrophone input hole 341, thespeaker output hole 331 and theback hole - However, it is noted that in another form of the present disclosure, in order to reduce the number of components and thus reduce the cost, a composition of a second
soundproof housing 302 is directly realized within the inside of afront surface case 200. - For an instance, though not presented in detail, like the second
soundproof housing 302 aforementioned, a speaker accommodation groove (not presented) for accommodating aspeaker 30, a microphone accommodation groove (not presented) for accommodating a microphone, a speaker output hole (not presented) adjacent to anoutput end 31 of aspeaker 30, amicrophone input hole 341 adjacent to aninput end 41 of amicrophone 40, at least a back hole (not presented) to make signals inputted into a rear surface of theinput end 41 of a microphone. - Herein, on a
protrusion portion 220 of afront surface case 200, components equipped at the abovementioned secondsoundproof housing 302 are formed. That is, an output guiding portion (not presented) that guides output signals from an output end of thespeaker 31 into aspeaker output hole 331, an input guiding portion (not presented) that guides input signals from amicrophone input hole 341 into aninput end 41 and a back hold guiding portion (not presented) that guides signals into a rear surface of a microphone through a back hole are formed on a protrusion portion of afront surface case 200, components equipped at the abovementioned secondsoundproof housing 302. - Herein, an input guiding portion, an output guiding portion and a back hold guiding portion, like the above embodiments, have a indented and stepped form on a
protrusion portion 220 of afront surface case 200. -
FIG. 11 is an exploded perspective view of the earset in yet another embodiment, andFIG. 12 is a perspective view for a formation of a housing main body and a rear surface of a protrusion portion of insertion inFIG. 11 . - In accordance with
FIG. 11 andFIG. 12 , anearset 10 b also comprises arear surface case 100 b, afront surface case 200 b, a soundproof housing 300 b and anear pad 400 b, and the detailed description for this composition is the same as one mentioned before. - As shown in
FIG. 3 , thesoundproof housing 300 comprises a firstsoundproof housing 301 and asecond housing 302, and is coupled within a space formed between arear surface face 100 b and afront surface case 200 b. - The
second housing 302 is separately formed into a housingmain body 310 and a protrusion portion forinsertion 320 so as to avoid issues that, when forming a speaker accommodation groove for accommodating aspeaker 30 and a microphone accommodation groove for accommodating amicrophone 40 in order to accommodate a speaker and a microphone within one soundproof housing in an integrated speaker and microphone system, output sound is too low and the quality of voice and sound is worsen. - In other words, in some embodiments, a speaker accommodation groove and a microphone accommodation groove are separately formed within each soundproof housing, wherein the speaker accommodation groove is formed as a dented shape with a constant depth on a rear surface of the housing
main body 310 so as to accommodate aspeaker 30, and the microphone accommodation groove is formed as a dented shape with a constant depth on a rear surface of the protrusion portion forinsertion 320 so as to accommodate amicrophone 40. - The housing
main body 310 and the protrusion portion forinsertion 320 are made of silicon, rubber or synthetic resins, and they make components equipped within aspeaker 30 and amicrophone 40 installed easily, block external noise and prevent sound from escaping to an externality. - A speaker accommodation groove for accommodating a
speaker 30 is formed on the housingmain body 310, and on a front surface it has a big hole from the speaker accommodation groove so as to deliver sound generated from the speaker to the inside of an ear and a small hole through which a microphone power cable or a microphone output cable passes. The hole's shape, size, number and location are available to variation. - A microphone accommodation groove for accommodating a
microphone 40 is formed on the protrusion portion forinsertion 320, and it has a big hole communicating with the big hole of the housingmain body 310 so as to deliver sound generated from the speaker to the inside of an ear and two small holes so as to deliver sound generated from the inside of an ear to themicrophone 40. It is apparent that its shape, size, number and location are also available to variation. - Each side of the surface of the housing
main body 310 and the protrusion portion forinsertion 320 has a groove for assembly with the case. - Like so, in accordance with soundproof housing for an earset and a wired and wireless earset comprising the same, an echoing or howling effect by the inflow of external noise is prevented, and oscillation noise by a speaker and a microphone is reduced, thus enhancing the sound quality.
- Moreover, a user easily and quickly combine a speaker and a microphone within a soundproof housing, and the assembly of a soundproof housing and a case improves and its internal airtightness also improves.
- In concluding the detailed description, it is noted that the description above is presented as illustration for the present disclosure in some embodiments, and those skilled in the art will appreciate that many variations and modifications can be made to the preferred embodiments without substantially departing from the principles of the some embodiments described above. Therefore, the described some embodiments are used in a generic and descriptive sense only and not for purposes of limitation.
